Abstract

The effect of Ca²⁺ on mycelial growth in Terfezia boudieri was studied. Terfezia boudieri Chatin (Ascomycotinae) occurs in mycorrhizal association with Helianthemum shrubs in deserts with calcareous soils. External Ca²⁺ stimulated mycelial growth in both liquid media and solidified substrates. The response to Ca²⁺ was very faint in well-aerated culture but pronounced in mycelia immersed in the medium, indicating dependence on mycelial aeration. 2,4-Dinitrophenol (DNP), an inhibitor of oxidative phosphorylation, and succinate, a potential cytoplasm acidifier, inhibited mycelial growth but enhanced the stimulatory effect of Ca²⁺. This effect was reduced by the Ca²⁺ channel blocker verapamil.
